The engaged nurse later said she felt “disgusted’” by his behaviour and said: “He was old enough to be my dad.”
Dr Tipo Qureshi, 44, has now been sacked from Sandwell General Hospital, in West Bromwich, and suspended from practising medicine for two months after being found guilty of misconduct.
A Medical Practitioners Tribunal Service hearing in Manchester heard he first told the 22-year-old nurse, known as Ms C, that she was his favourite.
The plastic surgery locum registrar also said: “It’s a shame you are engaged as I have a lot of money.”
But the hearing was told that, when he asked her on a date to a service station, he later claimed it was a joke inspired by a similar scene in the BBC’s Gavin and Stacey involving actor James Corden’s character Smithy.
Dr Qureshi was later sacked after claims he behaved inappropriately towards five women.
He has since apologised for his conduct.
The hearing was told the incidents occurred between September and December 2013 after Dr Qureshi had joined the staff at the hospital in the West Midlands from an agency.
He began commenting on the similarity of appearance between Ms C and an ex-girlfriend and when he asked her for a date she declined, saying she was “spoken for”.
But he later put his mobile phone in the face of Ms C and showed her a picture he had received via the dating website, Tinder saying: “She’s got a good pair of legs.”
Tribunal chairman Peter Scofield told Dr Qureshi: “You took advantage of the positional power inherent in that relationship. You made the comments on the ward and within earshot of other colleagues – an extreme lack of respect for Ms C.
“The tribunal found your actions were sexually motivated and you were consciously involving a junior colleague in an overtly sexualised conversation in the workplace.”
Dr Qureshi, of Warwick, was cleared of two separate allegations of intentionally touching the breasts of two other work colleagues during surgery on the same day.
